ALLISTON, Ont. - Ontario Provincial police say they've been unable to track down a man who shocked residents with a nude early-morning stroll through a town northwest of Toronto.

Police say they got a call early Friday about a man walking around downtown Alliston, Ont. (in the Queen St. area) without any clothes on.

Const. Tracey Bednarczyk says residents encouraged him to put clothes on, but the man seemed undeterred and continued casually walking through town in the nude.

Bednarczyk says the man was spotted in another area of town (near Albert St. and Centre St.) about 15 minutes later, but officers were unable to find him despite an immediate response to the area.

The suspect is described as white, in his mid-40s to early 50s, bald, standing about six feet tall and weighing between 190 and 210 pounds.

Bednarczyk says he may have left the scene in a newer model black pickup truck and the investigation is ongoing.
